I just got my alienware 14 and have exactly the same problem as you! The light on the bottom right is always on and causing weird colouring, I've tried doing everything on the thread and tried to find out how to reset the boot up sequence , but I just don't know how to do it... I'm getting really desperate here, any help is welcome!

ps: I have tried uninstalling/reinstalling the AWCC , the .NET (and making sure it's the right version etc.)

I have tried updating to the latest bios and have tried turning the light on and off, and of course tried the clean boot

First, try doing a Power Drain: Turn OFF the computer, unplug the AC adapter and remove the battery. Press and hold the power button down for about 45 seconds. Reconnect the battery and adapter and turn the computer back ON.

After that, run the AlienFXTester as explained on Solution #2 of this article.
